This is for status indication only. Typical hysteresis equals 140 mA. The thresholds are specified for supply voltage within the normal working range. 2 After cooling below the reset temperature the switch will resume normal operation. The reset temperature is lower than the trip temperature by typically 10 ˚C. 3 If the overtemperature protection has operated, status remains low to indicate the overtemperature condition even if the input is taken low, providing the device has not cooled below the reset temperature. 4 After short circuit protection has operated, the input voltage must be toggled low for the switch to resume normal operation. 5 Undervoltage sensor causes the device to switch off. Typical hysteresis equals 0.5 V. 6 Overvoltage sensor causes the device to switch off to protect the load. Typical hysteresis equals 1.1 V. 7 In a fault condition with the pull-up resistor short circuited while the status transistor is conducting. 8 The pull-up resistor also protects the status pin during reverse battery conditions.

This negative voltage is clamped by the device. 2 The load current is self-limited during the response time for short circuit load protection. Response time is measured from when input goes high. 3 If the load resistance is low, but not a complete short circuit, such that the on-state voltage remains less than VBL(TO), the device remains in current limiting until the overtemperature protection operates.
